DOZENS of people have stepped up to help Kirkwood Hospice.
The fundraisers sweated their way through three hours of aerobics yesterday .
The annual Aerobathon took place at Huddersfield Sports Centre with exercises including step, body combat and street dancing.
Kirklees Active Leisure organised the event.
Spokeswoman Rosey James said: "People were really up for it and the atmosphere was great."
Each participant paid £5 to take part, while some raised more through sponsorship.
Rosey hopes the event will bring in more than £2,000 for the hospice.
And it wasn't just exercise fanatics who were helping out the good cause.
Rosey, who took part herself, said: "Some of the participants are mega-fit and some of us are a little less so.
"When you finish you feel on a high, but a few hours later the pain and fatigue hits you."
